Progress of hybridization work at various centres in India is reviewed. With the improved technique of mango hybridization and the report of self-incompatibility in mango, it will be possible to evolve a larger number of hybrids for screening for desirable characters. Embryological studies have shown that in mango pollen tubes grow down the style and effect fertilization but the development of zygote is blocked leading to a sporophytic type of self-incompatibility. Hybrids recently evolved through the combinations of regular and commercial biennial bearing varieties indicate that largescale hybridization may offer a solution to the biennial bearing problem in mango.
